The EU Digital Identity Wallet Ecosystem offers a revolutionary way to manage digital identities and attributes (aka verifiable credentials), promising convenience, security, privacy preserving and cost savings for individuals and businesses. However, its success relies on addressing a crucial challenge: ensuring the system is fair and sustainable for all stakeholders (aka “the elephant in the room”). Wallet providers, trust service providers, and Electronic Attribute Attestation Providers will sustain most of the costs to build and maintain this ecosystem, while those who benefit most—like relying parties — may be more than willing to share some of the benefits they enjoy and pay for attribute verifications.

To unlock the full potential of the EUDIW ecosystem, it’s essential to create a market for electronic attributes. 

By assigning value to the verification of credentials and attributes, we can establish a system where those who benefit from using them—such as relying parties gaining faster, more secure processes—help sustain the ecosystem. This approach mirrors successful models already in place across the EU and EEA, ensuring fairness and incentivizing innovation.

Namirial, through its work in ETSI publicly announced just in January 2025 and thanks to many supporting organizations, is one of the leaders in shaping these standards. By fostering a balanced system where all parties benefit, we aim to create a thriving market for digital attributes—one that not only ensures privacy and security but also drives widespread adoption and long-term sustainability. This is the key to a successful digital future for Europe. 

The European Union Digital Identity Wallet (EUDIW) intends to give citizens control over personal data sharing. EUDIW users will have full and sole control over their data. The EU intends to address the risk to citizens’ privacy in cases where data from and about users is gathered and exchanged by online service providers.

However, it is unclear how users of the EUDIW can decide what data to share and how to prevent sharing too much data with online service providers. In order to reduce this risk, we need to understand it first.

Drawing on expert interviews, this talk presents a novel analysis of the risk of over sharing through the EUDIW. It defines the risk and what aspects influence the risk from literature, documentation and expert interviews. Over-sharing data occurs when users share more data than strictly required for the service or product acquired online and multiple aspects influence this risk, specifically the user capabilities and orientation, the loss of context awareness, the quality of the data and the ease of sharing.
